Bag of Bearing Ants

A bag of ball bearings enchanted with the carrying capacity of the common marching ant. When excited, they animate and carry impressive loads a short distance at the command of their user.

Using an action on your turn, you can lay these ball bearings across a level, square area that is 15 feet on a side. A creature crossing this area must succeed on a DC 13 Dexterity saving throw or fall prone. On your turn, you may command the ball bearings to transform into ant drones and carry prone creatures in their area in a direction of your choosing up to a maximum distance of 20 feet. A creature moving through the area at half speed doesn't need to make the save.
